Professional Applications & Engineering Value

This 1/4"-20 UNC 12-point screw in 450 Stainless Steel delivers critical performance advantages for demanding industrial applications. The combination of Class 3A thread fit and coarse threading ensures rapid assembly while maintaining vibration resistance in heavy machinery, construction equipment, and automotive systems. The external 12-point drive provides superior torque transmission compared to standard hex drives, reducing tool slippage and damage during high-torque applications. The flanged design eliminates the need for separate washers, distributing clamp load more effectively across joined surfaces. With 170,000 psi tensile strength and Rockwell C37 hardness, this fastener withstands extreme mechanical stresses while the stainless steel construction maintains integrity in corrosive environments, making it ideal for offshore, chemical processing, and outdoor infrastructure applications.

Specification Summary & Compliance

This 12-point screw features precision 1/4"-20 UNC coarse threading with Class 3A thread fit for superior dimensional accuracy. The partially threaded design provides 1" minimum thread length on a total 1-3/4" length with right-hand direction. Manufactured from 450 Stainless Steel with Rockwell C37 hardness and 170,000 psi tensile strength, it meets industry standards for heavy-duty fasteners. The external 12-point drive (5/16" size) and flanged design (33/64" diameter) comply with industrial fastener specifications for reliable performance in demanding applications.
